Fortunately a very small hurricane core of winds extending only 10 miles out. Still very impressive for late november though. What a year with Hermine and Matthew. I see the seasonal storm forecast was right on the money this year.

I may stand to be corrected , but I believe for the North Atlantic basin, Lenny still is the most intense latest tropical cyclone to have formed from November 13-23, 1999. Lenny reached 933 mb with 155 mph at his peak intensity.

EDIT:: I checked and forgot the 1932 November hurricane which formed and impacted Cuba. That storm is the most intense late season tropical cyclone ever on record in the North Atlantic basin. Lenny is the second strongest ever recorded for so late into the season.

Hurricane Kate in 1985 holds the record for the latest major hurricane that had formed in a season. It held the record for category 2 hurricane in the past as well, but this has just been broken by Hurricane Otto.

Yes you are right. It also will be not only the farthest south tropical cyclone to have ever developed, but soon to be major tropical cyclone to form in that region as well. Also, the eye is now beginining to clear out now on satelitte imagery with Otto.

Otto likely will be Cat 3 at landfall. Incredible to see a major hurricane here on Thanksgiving Day. Prayers to all down in Costa Rica and Nicaragua which will be impacted heavily by Otto.

In terms of southernmost, here is something I wrote earlier for my Facebook page based on the 4am EST Thursday track:

Based on Otto's forecast track and intensity, the hurricane is likely to become the southernmost landfalling hurricane in Central America according to NHC best track data in the Atlantic (since 1851) and East Pacific (since 1949). During those periods, no hurricane has ever made landfall in either Panama or Costa Rica. The southernmost landfalling hurricane in Central America during that period is Atlantic Hurricane Irene in 1971 (https://en.wikipedia.org/wiki/Hurricane ... 0%93Olivia). It made landfall with 75mph winds at a latitude approximately 20 nautical miles north of the latitude Otto is expected to make landfall at later today.

Among tropical cyclones that made landfall in Central America at a latitude south of where Otto is expected to make landfall, during the period the best track database is available for, there has only been one tropical storm landfall in Panama (Martha in 1969, 70mph) and one in Costa Rica (1887, 40mph). Among all tropical cyclones, there was also a landfalling tropical depression in Costa Rica in 1973 (35mph). Among the landfalling tropical cyclones in Nicaragua, the southernmost was Bret in 1993 (45mph). It made landfall near where Otto is forecast to make landfall. There have been no East Pacific landfalling tropical cyclones in Panama or Costa Rica. There was only one East Pacific tropical storm landfall in Nicaragua, Alma in 2008 with 65mph winds. (at a latitude about 75 nautical miles north of the latitude Otto is expected to make landfall at)

A lot of Americans there too who may be (or may have planned on) doing the Turkey dinner thing.

My oh my, I wish we had Recon in there right now. What a shame they are not down in there at this time that I can determine. Otto in my opinion is rapidly intensifying. The eye has cleared out as well and this has really become a powerful tropical cyclone. No doubt in my mind Otto will be a Cat 3 by landfall later this evening.

Actually there have been others further south in latitude. Not only in the rest of the Atlantic, but the SW Caribbean as well. Best track since 1851, with Otto's track. (the point at which Otto became a tropical storm or hurricane is not noted with a red dot, but you can tell from the best track data)

Here is the point at which a storm became a tropical storm:

Here is the point at which a storm became a hurricane...

Basin wide:

SW Carib:

That point at the start of Otto is not Otto but a storm in 1906.

You can see that Otto is second southernmost development of a hurricane in the SW Carib.

If you include the point at which something developed into a depression, including all tropical cyclones, there is even more south.

Finally, here is major hurricane development points...

Basin wide:

SW Carib:

So it would be the southernmost in the SW Carib, and tracking to be third southernmost basin wide.

Thanks in advance still learning how to read model data so any input welcome

There is no doubt the RI is ongoing and I agree Otto is on the way to a CAT 3 if not already there and only about 20 miles offshore. Incredible VIS images.
